It also breaks on Fedora 11 (rawhide)/gcc 4.4 on 32 bits directly (not
32 bit mode of 64 bits) on mplayer svn from more than a month ago (so
it's nothing new). I think this is gcc 4.4 specific.

Unfortunatley there is no bug at http://gcc.gnu.org/bugzilla/ filed
against 4.4.0 that contains GENERAL_REGS and seems to be related in
any way to this bug. Most probably the register starvation will be a
feature, e.g. gcc 4.4.0 makes better use of the registers and leaves
less for hand-assembly.
